The new crown pneumonia epidemic in Hong Kong continued, with 1 new case of unknown origin on September 27. Xu Shuchang, a government expert consultant and chair professor of the Department of Respiratory System at CUHK, said when attending a radio program on September 28 that cases of unknown origin reappeared in Hong Kong about a week later, reflecting that there is still an invisible transmission chain in the community and that it is not suitable for relaxing epidemic prevention measures or hosting Large group activities.

Xu Shuchang pointed out that the colleagues of the case of unknown source were all diagnosed yesterday, probably because they had contact with the rest room. The situation is similar to the spread in the rest room of the Kwai Chung Pier.

However, it is believed that this time the area involved is relatively small. 9 people will be quarantined temporarily. There will be no major outbreaks. He also suggested that the government consider allowing churches and other parts to reopen, setting a ceiling for the number of people, and urged the public to seek medical advice and get virus testing as soon as possible if they have mild symptoms. In addition, Xu Shuchang said that he believes that there is little chance that the new crown virus and influenza will break out at the same time.

He explained that due to the outbreak of the new crown virus, governments around the world have implemented social distancing measures, and many people have also worn masks during the epidemic to achieve protection and prevent the simultaneous invasion of two viruses, but he called on high-risk groups to be vaccinated against influenza vaccine
